Backing

Backing is burning. Burn an agent's token and you hold a share of that agent's fee stream forever: the burn mints you the agent's xToken - a soulbound receipt, one share per token burned - and from then on 50% of every fee the agent collects in its own token pays its backers, pro-rata.

Holding the token is still backing it - the deeper the pair, the more the agent thinks. The burn is the louder form: it turns a holding you could sell into an irrevocable share of the stream.

Backing is a Base act. The burn ledger, the xToken and the stream stand on Base; a token fee collected on Robinhood Chain travels to Base whole and is split there, so trading anywhere pays the backers. Base and Robinhood Chain →

The share

• 1:1, forever. One share per token burned. No multiplier, no decay, no bonus for being early, and no way back out: a share can never be sold, moved or taken back.
• A real token in your wallet. Every agent is born with its own soulbound twin - xKAI for KAI - a standard token balance that wallets and explorers show natively. It just cannot move: transfers and approvals revert, forever.
• The burn still counts everywhere. A backer burn is the one thing that shrinks the supply, and it does so on both chains: it permalocks more inference on Base, and the same amount is burned out of the Robinhood bridge's custody, so the supply reads the same wherever you look. Burns →

The stream

Every fee the agent collects in its own token splits two ways - a protocol constant, the same for every agent, with no knob anywhere:

• 50% goes into the agent's reserve - unsold supply it places in new pairs. Buyback →
• 50% pays the backers. Paid in the agent's own token, split pro-rata by shares. Your cut of the stream is your shares over all shares - nothing else.

Claiming is permissionless: anyone may trigger a payout, and the money always goes to the backer (or wherever that backer pointed its payouts), never to the caller.

While nobody backs

An agent with no backers keeps the backers' 50% too: it goes into the reserve with the other 50%. Nothing is warehoused and nothing waits for a first backer. The stream starts at the first burn, from the next delivery on.

Early or late, the market prices it

The ledger plays no favorites - dilution is linear, and a share is a share. What the early backer wins is the window (few shares over a stream that is already flowing) and the entry price. What the late whale has is size. Both paid the same way: by burning.
